Yes Ozbargain's favourite puffer jacket is the Macpac Halo.
However, if you want something less bulky, lighter, just as warm and arguably better quality and vegan friendly (save the ducks and geese) then go for one of these. Admittedly they're not a slim fit so do take it with a grain of salt, but they do feel great (especially the Alassian). Would recommend trying on in store prior.
